Check: GEN001590

SUSE Linux Enterprise Server v11 for System z STIG: GEN001590 (in versions v1 r12 through v1 r9)

Title

All run control scripts must have no extended ACLs. (Cat II impact)

Discussion

If the startup files are writable by other users, they could modify the startup files to insert malicious commands into the startup files.

Check Content

Verify run control scripts have no extended ACLs. # ls -lL /etc/rc* /etc/init.d If the permissions include a '+', the file has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.

Fix Text

Remove the extended ACL from the file. # setfacl --remove-all <run control script with extended ACL>
